sent me by my friend, Dr. Eis. In the wing-spots the differences 

 are as follows: — basal spot ciP. 2Mtricia narrower than in P. apollo, 

 but longer, reaching to beyond arculus and fourth antenodal, 

 (that of P. apollo does not reach the second antenodal), but not 

 keeping close to costa as in P. ajjollo. Second spot (intermediate 

 between base and nodus) smaller than in P. apollo, scarcely 

 touching the costa in hind wing and not at all in fore wing. 

 Another 7'oundish and someichat smaller spot interposed, in fore- 

 wing only, on the fourth antenodal from the nodus is found only 

 in P. patricia, and not in P. apollo. Third (nodal) spot shorter 

 and squarer than in P. ajjollo, covering only one postnodal instead 

 of two. On all four wings in P. iiatricia there is a fourth spot 

 jjlaced heloio the medAa.n nervure midway between the nodus and 

 pterostigma, covering two quadrilateral cells under the median and 

 two smaller pentagonal cells beneath. No such spot exists in 

 P. apollo. Fifth spot (under pterostigma) is placed in P. patricia 

 exactly under tlie pterostigma but is not quite so wide as it; in 

 P. apollo it is somewhat more rhomboidal in shape, and is placed 

 half before and half under the pterostigma. Sixth (apical) spot 

 slightly smaller than in P. apollo. All the spots in P. patricia 

 brilliant crimson with darker borders; transparent, and appear- 

 ing in a bright light as brilliant as a ruby. Spots of /*. apollo 

 (apparently) rich brown. 



As in P. apollo, so in P. patricia there are two rows of cells in 

 the postcostal area of the forewing. The pterostigma of P. 

 patricia is somewhat shorter than that of P. apollo. As regards 

 colouration, it is difficult to say what ma}^ be the true colours, in 

 life, of the Chilian species; but I have never seen any dragonfly 

 amongst the jEschnidcB which, in point of absolute beauty of 

 colour and pattern, could vie with P. patricia. The deep rich 

 reddish-brown of the abdomen, studded as it were with brilliant 

 gems in the shape of the numerous green spots and markings, 

 marks it out as standing alone amongst the jEschnidce for absolute 

 beauty; while the wonderful display of transparent red light in 

 the wing-spots is quite unparalleled in that family. We may 

 expect the male, when discovered, to be no exception to the 

 general rule, but to outvie even the beauty of the female. >*'''''T»"^^^^*"^*'\
